Specification. of Letters Patent.-

Patented March 5, 1907.

Application filed August 31, 1,906. SerialNo. 332,785.

Be it lm'own that we, GUILLIAM H. CLAME and CHARLES F..HOPKINS, bothcitizens of the United States, and residing in the city of Philadelphia,county of Philadelphia, and State'of Pennsylvania, have jointly inventedcertain new and useful Improvements in Railway Journal-Bearings, ofwhich the following is a' specification.

it is inade, both'being coordinately impor'-' tant; and. the object ofthe invention is to 'provide a hearing which shall be light andtherefore comparatively inexpensive, ,yet

possessed of suflicient mechanical strength licable or cooperationandwhich-shall be a with the American, aster OarBuilders.Associationpresent standard box and wedge.

The nature, characteristic features, and scope of our inventionw'ill bemore fully understood from the following description, taken inconnectionwith the-accompanying drawings, forming part hereof, and in Which-Figure 1 is a longitudinal central section of a journal-box andcontained parts embodying features of the invention. Fig. 2 is, a top orplan view of a bearing detached from the journal-box and embodyingfeatures of the invention. Fi .3 is a side elevational View ig. 4 is atransverse sectional view taken on the line 4 4 of Fig. 2; and Fig.

5 isa sectional view, on a reduced scale,-of the Wedge. g

Internally the form of the bearing is semicylindrical, as 'at l, andexternall. the form of the bearing is semicylindrioa i as at 2. Upon theexterior of the bearingthere are arranged semipolygonal flanges, ofwhich three are shown, one, 3, being arranged at one end,

another, 4, in the center, and the third, 5, at.

the other end. The three flat surfaces 6, 7, and 8 of these flanges, aswell as the flat surface 9, of a longitudinally-ran ingcentrallydisposed flange 10, impart to t e structure a generallysemipolygonal back. The bearing is shownas provided with the usualupturned flange 11 and with lateral extensions 12.

The described bearing is constructed of mang'anese bronze orequivalentmetal, which is relatively very hard and strong, and. thebearing is internally faced-with a bearing metal, as lead or lead alloy,which is rela-,

tively' soft and weak.

The s aces between the rim and projectionslig ten the structure, so thatcomparatively little metal is required for making it, while at the sametime the semipolygonal projections andthe lengthwise-ranging rib and thematerial em loyed not only impart sufficient mechanical strength to thestructure, but also give it the shape or form and dimensions. requisitefor mounting, fitting, and holding it betweenthe journal -14L and thesuperposed wedge 15, which is provided with a semipolygonal face and isarranged form prescribed as standard by the American Master Car-BuildersAssociation.

Having jects of our invention, what we claim as new, and desire tosecure by LettersPatent, is

A hearing consisting of metals whereof one is relatively weak and softand the other is relatively strong and hard and comprising a insideofthejournal-b03016, which is of the thus described the nature andobsemicylindrical portion having uponits exterior semipolygonalprojections arranged at and intermediate of its ends and having acentrally-disposed projecting rib, the upper faces of said rib andprojections constituting a plain semipolygonal surface in combinationwith a journal-box for containing the bearing and with a wedge having asemipolygonal face and interposed between the ournal-boxand saidsemipolygonal surface,

substantially as described.

In testimony whereof we have hereunto signed our names in the presenceof two witnesses.
